Question

Reorder the steps in the production of urine in the urinary system.

a) The ureters filter the bloodstream first, producing urine.
b) The urine travels down the urethra to the kidneys.
c) The urine remains here before being released from the body during urination.
d) It flows through the bladder to exit the body.

Answer 1

The correct order of urine production is: filtration by the kidneys, transportation by the ureters to the bladder, storage in the bladder, and excretion through the urethra.

Step-by-step explanation:

The correct order of steps in the production of urine in the urinary system is quite different from the order given in the question. Here's how the process actually works:

1. Kidneys filter the blood, removing excess water, salts, and nitrogen-containing molecules, forming urine.
2. Ureters transport the urine from the kidneys to the urinary bladder.
3. The urinary bladder stores urine until it is ready to be excreted from the body.
4. Upon urination, urine travels through the urethra and exits the body.

Therefore, the corrected order is:

1. Kidneys filter the bloodstream, producing urine.
2. The ureters carry the urine from the kidneys to the bladder.
3. The urine is stored in the bladder before being released.
4. It flows through the urethra to exit the body.
